It has been nearly two years since Libyan dictator Moammar Gadhafi was ousted from power and killed by rebels.
His son, Saif al-Islam Gadhafi, who was the public face of his father’s regime during the revolution of 2011, was captured in the Libyan desert late that year.
Since then, he has been held in the town of Zintan, which was a hotbed for the opposition to his father. High up in the Nefusa mountains of western Libya, few places suffered more than Zintan during the Libyan revolution.
Rebels from the town helped liberate Tripoli in the summer of 2011.
Saif Gadhafi faces charges of crimes against humanity, but there has been a fight over where to try him.
The International Criminal Court in the Hague has tried to extradite him, but Libya has resisted and plans to put him on trial next month.
